| Thermo-mechanical analysis of problems involving unilateral contact between two bodies. Coulomb dry friction law is used. The contact condition is enforced via a penalty method or augmented Lagrangian method according to ISTRA(4). Heat transfer between the bodies depends upon the contact state. \\ | Thermo-mechanical analysis of problems involving unilateral contact between two bodies. Coulomb dry friction law is used.
